Interação entre as vias de sinalização de receptores serotoninérgicos e Β-adrenérgicos em artéria femoral de ratos

Fundamento: A doença coronária tem sido amplamente estudada em pesquisas cardiovasculares. No entanto, pacientes com doença arterial periférica (DAP) têm piores resultados em comparação àqueles com doença arterial coronariana. Portanto, os estudos farmacológicos com artéria femoral são altamente relevantes para a melhor compreensão das respostas clínicas e fisiopatológicas da DAP. Objetivo: Avaliar as propriedades farmacológicas dos agentes contráteis e relaxantes na artéria femoral de ratos. Métodos: As curvas de resposta de concentração à fenilefrina contrátil (FC) e à serotonina (5-HT) e os agentes relaxantes isoproterenol (ISO) e forskolina foram obtidos na artéria femoral de ratos isolada. Para as respostas ao relaxamento, os tecidos foram contraídos com FC ou 5-HT. Resultados: A potência de classificação na artéria femoral foi de 5-HT > FC para as respostas contráteis. Em tecidos contraídos com 5-HT, as respostas de relaxamento ao isoproterenol foram praticamente abolidas em comparação aos tecidos contraídos com FC. A forskolina, um estimulante da adenilil ciclase, restaurou parcialmente a resposta de relaxamento ao ISO em tecidos contraídos com 5-HT. Conclusão: Ocorre uma interação entre as vias de sinalização dos receptores β-adrenérgicos e serotoninérgicos na artéria femoral. Além disso, esta pesquisa fornece um novo modelo para estudar as vias de sinalização serotoninérgicas em condições normais e patológicas que podem ajudar a compreender os resultados clínicos na DAP.

Genetic determinants of methicillin resistance and virulence among Staphylococcus aureus isolates recovered from clinical and surveillance cultures in a Brazilian teaching hospital

Aims. To quantify the presence of SCCmec types and virulence genes among Staphylococcus aureus colonizing and infecting patients from a teaching hospital. Methods. We analyzed 225 and 84 S. aureus isolates recovered from surveillance and clinical cultures, respectively. Strains were studied for the presence and type of SCCmec, as well as for several virulence genes. Univariate and multivariable analysis were performed in order to identify predictors of invasiveness (defined as isolation from clinical cultures). Results. The presence of SCCmec types III (OR, 2.19, 95% CI, 1.08-4.45) and IV (OR, 5.28 95% CI, 1.35-20.63) and of genes coding for exfoliative toxin B (etb, OR, 6.38, 95% CI, 1.48-27.46) and Panton-Valentine leukocidin (pvl, OR, 2.38, 95% CI, 1.16-4.86) was independently associated with invasiveness. Conclusions. SCCmec types III and IV and virulence genes are associated with greater invasiveness of S. aureus. Patients colonized with methicillin-resistant S. aureus, as well as with strains harboring etb or pvl, may be prone to develop invasive disease. Infection-preventing strategies should be more intensively applied to this group.

Evaluation of the temporal acoustic window for transcranial doppler in a multi-ethnic population in Brazil

The aim of this study was to relate the presence of a temporal acoustic window (TAW) to the variables sex, age and race. This observational study was conducted in patients under etiologic investigation after stroke, sickle-cell anemia and hospitalization in an intensive therapy neurologic unit. TAW presence was confirmed by bilateral assessment by two neurologists via transcranial Doppler (TCD). Multiple logistic regression was performed to explain the presence of the window as a function of sex, age and race. In 20% of the 262 patients evaluated, a TAW was not present. The incidence of TAW presence was greater in men (odds ratio [OR] = 5.4, 95% confidence interval [CI] = 2.5-11.7, p < 0.01); lower with increased age (OR = 0.9, 95% CI = 0.92-0.97, p < 0.01); and lower among those of African and Asian descent (OR = 0.32, 95% CI = 0.14-0.70, p = 0.005). On the basis of the results, more men than women had TAWs, and the decrease in TAWs was associated with increased age and African or Asian descent.

Association between concurrent genital bleeding and cervical cancer: a cross-sectional study

Genital bleeding may be a common symptom among women with cervical cancer. Cross-sectional study evaluating whether the prevalence of cervical smear results is different in women with and without clinical information about concurrent genital bleeding. The sample consisted of 2 324 836 smears; of these, 0.4% had clinical information on genital bleeding. When stratified by age group, women with genital bleeding had a higher chance of a cytological result of a high-grade squamous intraepithelial lesion [30-49 years odds ratio (OR) 2.38; 95% confidence interval (CI) 1.60-3.53 and ≥50 years OR 6.30; 95%CI 3.72-10.67), of squamous cell carcinoma (SCC) (30-49 years OR 24.70; 95%CI 11.96-51.03 and ≥50 years OR 48.91; 95%CI 31.28-76.47) and of atypical glandular cells (30-49 years OR 5.72; 95%CI 3.30-9.93 and ≥50 years OR 11.56; 95%CI 5.96-22.45); there was also a higher chance of adenocarcinoma for women ≥50 years (OR 53.13; 95%CI 28.08-100.51). The sensitivity of genital bleeding for women aged 18-29 years was 0.4% for high-grade squamous intraepithelial lesion (HSIL); for women 30-49 years old the rate was 0.9% for HSIL, 8.6% for SCC and 2.1% for atypical glandular cells of undetermined significance (AGUS), while for women aged from 50 years or more the rates were 2.0% for HSIL, 13.7% for SCC, 3.6% for AGUS and 14.7% for adenocarcinoma. Women ≥30 years old with genital bleeding should be referred for colposcopy to rule out the possibility of cervical cancer.

Ética e atuação profissional: percepção de agentes comunitários de saúde

The perceptions of the Community Health Agent (CHA) referred to ethics in their work have been evaluated in this study. A questionnaire with social and ethical issues was applied in 61 ACS. 90% reported having received information about ethics, and “training courses” was the most cited source (68.9%). On a scale from 1 (least) to 5 (maximum), 67% claimed to have knowledge about ethics among 4 or 5 and 88.5% reported that this topic has an importance of 5 in their work. Ethical conflicts exposed had an average of 75% of respondents in agreement with the reference sources, and the two items involving “information privacy” showed the greatest disagreement. Ethics was considered important by the professional performance of subjects who had a good perception about the issue; however the topic about privacy of information generated controversy.

Infecção do trato urinário adquirida em ambiente hospitalar em idosos

Introduction: Hospital-acquired urinary tract infection (HAUTI) is an important cause of morbidity in the elderly population. Objective: Evaluate the occurrence of HAUTI and risk factors associated with it. Method: This is a prospective study of a sample of 332 elderly people, interned in a university hospital. Criteria for defining infection were established by the Center for Diseases and Prevention Control. Statistical analysis of data used calculation of frequencies, odds ratio and logistic regression. The rate of hospital infection was 23.6%. The prevalent topographies of infection were respiratory infections (27.6%), urinary tract infections (26.4%) and surgical wound infections (23.6%, with 21, 20 and 19 episodes, respectively. The HAUTI incidence density associated with urinary catheterization was 24.2 infections by 1,000 catheter-days. The length of hospital stay of patients without nosocomial infection was 6.9 days and with HAUTI was increased in 10.4 (p<0.05).The rate of mortality of patients with HAUTI was 20%. Pathogens were isolated in 75% of episodes of HAUTI and the prevalent were: Escherichia coli (33%) and Pseudomonas aeruginosa (20%). Risk factors found for HAUTI were urinary catheterization implementation (odds ratio (OR) = 43.1; 95% confidence interval (95 CI%) = 3.9 – 311.1), hospitalization with community infection (OR= 21.9; 95% CI = 4.9 – 97.9); vascular diseases (OR=14; 95% CI = 2 – 98); diabetes mellitus (OR= 5.5; 95% CI = 1.4 – 21) and urinary catheterization by more than three days (OR=3.7; 95% CI = 1 – 13.8). Conclusions: HAUTI presented elevated incidence and it increased the length of hospital stay.
